When the blonde gaurdian comes back, you use a Jedi Mind Trick and
say, "You will give us our clothes and a potion to let us be able
to grow up." The guardian gives you the potion, but says,
"You'll have to get your own clothes."
When the two gaurdians are gone, you turn to Obi-Wan. "I sense
something in these people. Something very, very bad." Obi-Wan
nods in agreement.
